2. Description of the Background Art
A magnetic recording/reproducing device or a television comprising the magnetic recording/reproducing device is known in general, as disclosed in Japanese Patent Laying-Open Nos. 8-56318 (1996) or 8-249872 (1996), for example.
The aforementioned Japanese Patent Laying-Open No. 8-56318 (1996) discloses an electronic apparatus (television) in which a holder (holding member) with a video cassette recorder (magnetic recording/reproducing device) and a printed circuit board placed thereon is assembled along a guide rail provided in a front cabinet and thereafter the front cabinet is assembled with a rear cabinet.
The aforementioned Japanese Patent Laying-Open No. 8-249872 (1996) discloses a magnetic recording/reproducing device, in which a hole formed in a circuit board is fitted with an inwardly-protruding projection of a cabinet, whereby the circuit board is located in the cabinet, and thereafter a connector provided in the circuit board and a connector provided in a magnetic recording/reproducing portion for recording and reproducing a magnetic tape are connected to each other.
In recent years, with digitization of information, a DVD (Digital Versatile Disc) recordable digital data and the like are in widespread use as an alternative to a recording medium such as a magnetic tape recordable analog data. Therefore, various disk units capable of recording and reproducing digital data are proposed as a recording/reproducing device alternative to a magnetic recording/reproducing device, as disclosed in Japanese Patent Laying-Open Nos. 2005-228465 and 2004-280917, for example.
The aforementioned Japanese Patent Laying-Open No. 2005-228465 discloses an optical disk player (disk unit) comprising a body, a tray conveying an optical disk such as a DVD recordable digital data inside the unit, a pickup drive portion (drive portion) capable of turning upwardly and downwardly in order to load the optical disk conveyed inside the unit, a door openably/closably mounted in a portion where the tray moves into and out of the unit and inhibiting dust or the like from penetrating in the unit.
The aforementioned Japanese Patent Laying-Open No. 2004-280917 discloses a disk unit comprising a tray for conveying an optical disk such as a DVD inside the unit, and a pickup drive portion (drive portion) having a mechanism of turning upwardly and downwardly in order to load the optical disk conveyed inside the unit. In the disk unit disclosed in the Japanese Patent Laying-Open No. 2004-280917, when the optical disk conveyed inside the unit is loaded, a damper provided in the pickup drive portion is brought into contact with a lower surface of the tray, thereby inhibiting a noise from generating with rotation in loading the optical disk.
The disk unit-integrated television (DVD-integrated television) comprising the disk unit as disclosed in the aforementioned Japanese Patent Laying-Open Nos. 2005-228465 or 2004-280917 is also known.
The exemplary conventional DVD-integrated television 100 comprises a front cabinet 101, a rear cabinet 102 and a CRT (cathode ray tube) 103 as shown in
A holder 104, a circuit board 105 arranged on an upper side of the holder 104, a DVD drive unit 106 arranged on an upper side of the circuit board 105 are provided inside the outer frame constituted by the front cabinet 101 and the rear cabinet 102, as shown in
The DVD drive unit 106 includes a DVD drive unit body portion 106a, a disk tray 106b for conveying a DVD (not shown), a pickup drive portion 106c provided with a motor (not shown) serving as a driving source sliding the disk tray 106b in an anteroposterior direction, an optical pickup (not shown) for recording and reproducing data and the like. The pickup drive portion 106c is so formed as to turn downwardly in order not to hinder movement of the disk tray 106b when the disk tray 106b moves, while turning upwardly in order to receive a DVD from the disk tray 106b when the DVD is loaded. The DVD drive unit 106 is set in the supporting portions 104a of the holder 104 protruding by a position having a prescribed height from the circuit board 105. Therefore, even in a case where the pickup drive portion 106c turns downwardly when the disk tray 106b moves, the pickup drive portion 106c can be inhibited from coming contact with the circuit board 105.
In the conventional DVD-integrated television 100 shown in

According to this structure, the second circuit board can be inhibited from protruding in a direction away from the first circuit board (upwardly), as compared with a case where the second circuit board is arranged in a tilted state with respect to the first circuit board. Thus, it is possible to enhance a freedom degree of arrangement of an apparatus arranged above the second circuit board.
In the aforementioned structure in which the third circuit board is so mounted on the first circuit board as to extend in the substantially perpendicular to the surface of the first circuit board, the holding member preferably includes a guide portion protruding upwardly and holding a side portion of the third circuit board, the first circuit board preferably includes a first receiving hole receiving the guide portion of the holding member, and the third circuit board is preferably held by being guided with the guide portion inserted into the first receiving hole and protruding above the first circuit board.
